13 years agoStratixI maximum input current
Hi, I'm looking for information about the absolute maximum input current a pin can handle before damage and the maximum current the PCI-clamp diodes can support. I'm using an EP1S60F1508 and I n...

13 years ago1. There's no maximum rating of PCI clamp diodes specified in the datasheet. Considering that the -25 mA output current is related to the high side transistor, I would also try to keep 25 mA for the clamp current.
2. Don't forget that the PCI clamp diodes are disabled between power on and configuration end.
